Jerusalem artichoke can propagate with seeds and tubers but the use of tubers leads to higher yields. For the plantation of Jerusalem artichoke the tubers are cut into pieces with three to five buds that are placed in 5-10 cm depth in the soil. Jerusalem artichoke have low nutrient requirements and need less nitrogen than other energy crops. The competitiveness against weeds is high which makes the weed control easier but also makes it harder to grow a new culture after Jerusalem artichoke since usually small pieces of tubers remain in the ground after harvest. Reasons for the high competitiveness could be the allelopathic effects, the high plant size and the rapid growth rate of Jerusalem artichoke.
